Filed: 1979-09-28
Abstract: PURPOSE:To charge into a blast furnace a hopper-stored raw material in accordance with the  target number of chute rotation by a method wherein how much the flow-control valve to be  opened at the next time is calculated by examining the past information data on the number of  chute rotation accumulated at a constant rotational speed, and on the information how widely the  same valve be opened at the preceeding time. CONSTITUTION:Hoppers 1, 1' are installed with detectors 11, 11' such as an acoustic detector  capable of accurately measuring the time at which a base material is charged. A circumferential  location detector 7 is used to detect the number of rotation of the rotary chute 14 during a time  interval detected by the detectors 11, 11', and its pulse number is counted by the detector section  B. If, for example, the degree of opening of flow control gate valves 2, 2' is to be controlled at a  constant rotational speed, then the calculator section B uses the detected B rotational number and  a preliminarily set A target rotational number to calculate the error of opening of the flow control  valves between the calculated and actual values. The instruction of how much the valve to be  opened at the next time is calculated from the above calculation value, the charged amount from  the hoppers 1, 1' and the corrected opening degree of the valves 2, 2' at previous time both given  from the memory section D, and the previous instruction on the opening degree of the valves.
